Thread: An assignment problem

Hi I've this string tokenizer assignment problem. I want to do this by myself but juz need some advise to get started.

Given a header file with these function protoypes:

Code:

typedef struct strTokenizerRec *stringTokenizer;

stringTokenizer createStringTokenizer(char[], char);
// pre: true,
// post: return a stringTokenzier for char[] with char as delimiter

int countTokens(stringTokenizer);

int hasMoreTokens(stringTokenizer);

char* nextToken(stringTokenizer*);

void destroyStringTokenizer*);

void displayLine(stringTokenzier strT);

What is the use of createStringTokenizer()? My understandin is it required 2 arguments, 1 is an array and the other is a char and it return a stringTokenizer.

My input would be something like XXX~XXX~XXX~ after readin from a file. Am I correct to say that the array is the XXX~XXX~XXX~? How abt the char? What would be the output of the stringTokenizer?

Heap tks....

Well it appears before you can call nextToken(), you must create a stringTokenizer struct. So you take the array and delimiter, and return a stringTokenizer struct. So the first question is: what is contained within a stringTokenizer struct?
